The filter was applied on bearing estimates from the acoustic data and estimates of the target position from the electrode array. The results show the positions of the targets are gained by fusion between the acoustic bearing and the electrode sensors, within the limits of their sensitivity","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128390120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process of situation and impact assessment involves dynamic generation of hypotheses about the states of the environment and evaluation of their plausibility via reasoning about situational items, their aggregates at different levels of granularity, relationships between them, and their behavior within a specific context. This paper addresses the problem of reasoning for situation and impact assessment to support early-phase crisis management. Special attention is paid to \"inference for best explanation\" aimed at discovery of the underlying causes of observed situational items and their behavior, an important component of situation and impact assessment. The presented method of discovery of underlying causes is illustrated by the discovery of an unreported HAZMAT incident within an early-phase earthquake response scenario","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130535672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We focus on a relevant class of problems where state estimation can be viewed as a classification of possible states based on the fusion of heterogeneous and noisy information. We introduce the inference meta model (IMM), a coarse runtime perspective on the inference processes which facilitates the analysis of the state estimation with BNs. By making coarse and realistic assumptions, we show that such inference can be very robust and has asymptotic properties regarding the fusion accuracy, even if we use models and evidence associated with significant uncertainties. Moreover, the IMM provides guidance for the development of (i) robust fusion systems and (ii) methods for runtime detection of potentially misleading fusion results","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126365252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From a command perspective, this refers to the allocation of friendly and coalition force elements (e.g. fighter aircraft, frigates etc.) to engage or interdict adversaries which are posing threats, not only to themselves, but also to defended areas and high-value assets. In an earlier work, a conceptual rule-based approach to weapons allocation in the air domain was outlined in terms of so-called critical and sorting parameters, which may be used to determine the capability of each friendly airborne interceptor to engage or counter each threat, and to rank the candidate interceptor-threat pairings respectively. An issue of relevance to the evaluation of the (interdependent) parameters of fuel sufficiency, egress safety and time-to-intercept is how to determine the shortest path from a given interceptor to a static or dynamic threat which avoids prohibited areas such as missile engagement zones, neutral and enemy territories and other exclusion zones. However, in general finding the shortest path is a non-trivial exercise and so determining sub optimal paths through the prohibited areas is often necessary. In the current paper, the problem is investigated from both perspectives. In particular, a technique developed for, and applied to, the field of robotics for finding the shortest path from a source to a fixed destination through a flat earth environment littered with obstacles is adapted to solve the shortest path problem for a spherical earth geometry. This is then used as the basis for determining efficient paths from an interceptor to engage or counter a moving threat","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131828530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These new systems enable downlinking several aircraft parameters for use in ground air traffic management (ATM) systems. Some of these parameters can be used for ATM system function enhancements, such as aircraft tracking. Thus, in this paper, a robust architecture is proposed using downlink airborne parameters (DAPs). This architecture consists of two filters in parallel: one is in charge of dealing with DAPs and the other one cope with the absence of them. Results showing the improvements in performance of the whole system are presented, as well as results coming from the DAP based filter alone.
